avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...

OBJECTIVE To determine whether M mode echocardiography can differentiate fetal supraventricular tachycardia according to the ventriculo-atrial (VA) time interval, and if the resulting division into short and long VA intervals holds any relation with clinical presentation, management, and fetal outcome. DESIGN Retrospective case series. SUBJECTS 23 fetuses with supraventricular tachycardia. ...

Differentiating ventricular tachycardia from other broad complex tachycardias is important both for the management of the acute arrhythmia and for long term treatment to prevent its recurrence. In our experience ventricular tachycardia is often mistaken for supraventricular tachycardia, and clinical bias in favour of supraventricular tachycardia is strong. Ia Several arrhythmias may give rise t...

Hydrops fetalis is defined by the accumulation of fluids in serous membranes (pleurisy, ascites, pericarditis...), it a rare condition; its etiologies are divided into immunological and non-immunological. Supraventricular tachycardia remains known cause, non-immunological, but difficult to manage.
 In this article we report case newborn with hydrops secondary supraventricular tachycardia, ...

Any tachyarrhythmia arising from the atria or the atrioventricular junction is a supraventricular tachycardia. In clinical practice, however, the term supraventricular tachycardia is reserved for atrial tachycardias and arrhythmias arising from the region of the atrioventricular junction as a result of a re-entry mechanism (junctional tachycardias). The most common junctional tachycardias are a...

Twenty-two consecutive patients underwent esophageal stimulation and recording for the diagnosis and management of supraventricular tachycardia. In 13 of these patients, the resting electrocardiogram was normal and in nine it showed pre-excitation. Of the 13 patients with a normal resting electrocardiogram, supraventricular tachycardia was initiated in all. Seven patients had a ventricular-to-a...

OBJECTIVE To study various types of supraventricular arrhythmias in patients with Brugada Syndrome. METHODS Forty six patients with ECG of spontaneous type Brugada and with ventricular and/or supraventricular tachyarrhythmia, without structural heart diseases which were excluded by echocardiography, underwent 24 h-Holter recording, electrophysiological study and/or radiofrequency ablation. ...

BACKGROUND Ambulatory outpatients (n = 150) with a history of paroxysmal supraventricular arrhythmia were studied to establish the characteristics of the first recurrence of symptomatic tachycardia (time to first recurrence, heart rate during tachycardia, and observed rhythm that was regular versus irregular) when no antiarrhythmic drug was being taken. Baseline variables were examined to asses...
